my personal experience......when i first visited the sale office and asked about samm unit......the sale person will let you know what are the requirements, then we just furnished them with the required info and documentation so they can submit for us (this is few weeks before the launching/balloting day)  i will follow up with them on and off, then they update us if we are qualify or not.....if qualify then during the balloting day just present yourself and follow the instruction on how to ballot the unit.......i might be wrong or this may not be the standard procedure, this is base on my experience for serasi's samm unit.......cheers
